I am attaching the installation manual for the E90 BT retrofit. Ther are two files, one for a pre-wired car and one for a non pre-wired car. I am told that cars come pre-wired for BT in the US if they have I-drive? however, the file that is for pre-wired cars, details how to install a BT Aerial, Hands-Free Microphone, and other entities that I thought already come installed on the E90 with I-Drive? Any thoughts?

Thanks,

I have an E90 (2006) without preparation. What Bluetooth car kits are best suited to my car, besides the BMW kit? Can I install this kits myself?

[cdxp]

I have "with prep" so kind of interested in this - however looking at instructions requires the inevitable software upgrade so i would guess DIY not possible.

Who can I have install this? I live in So. Cal. I spoke with Savage BMW and they told me it was not posssible to add Bluetooth to my 325I e90

thanks for this. I have a no pre-wired car, how much is the part? And also, when speaking of reprogramming - does that mean the whole ECU or just some part of it? I am thinking of getting a remap, would such dealer reprogramming wipe that out?
thanks for answers.

I found the kit on Ebay. He has both for pre-wire and non pre-wire.

Now, that I have done the retrofit I can report to you how it worked:
My car was prewired. So everything was Plug & Play.
In the trunk I only had to connect the 3 wires. No problem. Watch out, that you buy the right nuts for the bracket. My dealer gave me wrong ones.

Installing the BT antenna is also very simple. Open the three screws under the steering wheel and open the compartment. Now you can clip in the antenna and connect it to the wire.

Installing the mic is a bit more difficult, because you have to remove the roof control center. I used a very small screwdriver to clip it out. But there are several ways described in the forum. Removing the blind plate is a bit difficult but with two very small screwdrifers you can clip it out and lift it.

Now the most difficult part: The rear backrest...
First remove the backseats. You just have to pull it up and it clips out.
Under the armrest there are two big T20 or T25 screws. You need a big tool or much armpower to remove them. But be carefull!!!
Then you have to go into the trunk. There are two holes, the emergence exit . Put in a screwdriver and turn the little plate till the backrest jumps out.
Now you have to take it out. Don't try to pull it towards the front seats and work with the backrest still in the car.
On the right side there are the Most-Bus connectors. Just follow the green cables. Remove them and try to clip the covers out. They are very hard to seperate. I broke both of them so better buy two new ones at your dealer...
Now you just have to disconnect one wire of each connector and put it into the other connector. Use a small screwdriver for that.
Now why you had to remove the backrest completely: Clean the holes for the screws. They are fitted into the holes with some sort of glue. You have to remove it completely.
Then put in the backrest and clip it into the "emergency exit". Now put in the screws. But be careful! I destroyed one of the threads...the screws are very hard and the threads are very soft. But it also works with one screw in place

Now you have to go to your dealer and reprogram the retrofit.

Sounds difficult.
Any pics?

[basti313]

Hmmm...difficult. Its VERY difficult to get the roof control center out and the screws of the backrest in. The rest is plug and play.

I don't have pics. Nothing interesting...removing the roof c....is already described with pics in the forums and the rest is not worth making pics

What part numbers did you need, where did you get them?

How much did this cost in total?
Does the BT work the same as factory installed?
Does this link with the Idrive the same way.. ie contact list etc. ?

I'm very interested in doing this.

[basti313]

The retrofit is working exactely the same as factory installed.

The most expencive things are the control module and the eject box. I bought them via Ebay for 130Euro.
Additionally you need the BT-Antenna, the microphone and the brackets for control module and eject box. Together 60Euro. I bougth these thing at my local dealer. You can get the part numbers here: http://realoem.com/bmw/
Programming the vehicle costs 114Euro.
Total: 304Euro ~ 235$

How can you tell if your vehicle is pre-wired for bluetooth. I have a 2006 e90 with no premium, no i-drive and no BMW assist. Is there any markings? Are all cars in the USA prewired?

All US e90 are pre-wired.

The link doesnt work for me. Could you list the part numbers?
I am definitely considering doing this.

Also, how is this different than the BT kit on ebay for ~$1000?

Sound like a fun dyi. I am very sure you are very happy with the bt. I noticed that you are in germany and you have a 320D. On my US 330i, the 2 screws you are talking about under the rear armrest are T-50 (not sure about europe model). Yes, they are big and the threads on them are very soft. I too destroyed one of my screw (right one on driver side). You just need to get another screw from dealer or just use 1 screw (thus reducing weight ). My car already came with bt already activated so i did not do this but sounds like an awesome dyi and wanted to share some photos for those photo freaks...

enjoy.

Yeah what's the difference for the kit that roveractive sells and what the guy in Germany bought? Is the expensive kit from roveractive necessary if the car isn't prewired?? If part numbers are listed I'll be buying tonight lol. I love the BT in my dad's 330 so my car has to have it if it costs under $400US.

[DrPowers]

I currently have my dealer looking into it. He definitely knew it was possible and said they had done it before.

Oh dude you gotta let me know what happens. I have prolly one of the coolest dealers/SA's that love doing extra mods for me. They already did the halogen to xenon swap for me so adding the BT should be a walk in the park . I just left a message with me SA so I'll see what he says as well.

that halo to xenon is next on my plate... he's supposed to call me back within the hour to quote me on a price. It will most likely be very high and I'll end up doing the part install myself and leaving the activation to them.

This is what happened with the car alarm.

[darkcloud]

Yea I'd do the install of the BT myself, I just need the part numbers. I let the dealer do the xenon swap, they charged me 1k for install, footwell module, and programming. They are currently looking at adding another wire today to make the highbeams work properly. Once thats done my xenon swap will be the first done that are fully functional and w/o an error.

The bonus about letting them do the xenon swap is the tech did a better job then most of the people who did them on their own. He got a faulty harness and used the plugs to add the wires. This way everything is completely waterproof and looks perfectly stock. I feel the 1k was more than worth it.
